This is correct, while I do not agree with the idea of copying someone else or relying completely on them if someone is looking to do something like this then it is a huge mistake to think they are going to find a legitimate group at telegram of all places, when we know the place is full of scammers which want nothing but to get your money through all means possible, so if someone is looking for something like this their best bet is to use an exchange with this feature.
There are features that allows copy trading but it's not that good at all if someone will rely on completely. That's a wise strategy if we're going to think of it.
But doing that, you'll eventually realize that it doesn't look good if you'll be copying others way of trading because it might not work for you.
I guess for starters, it's a good way to start trading but if you've already learned the basics, make your way to your own strategies.
I think this will be much better when the general market is on a good move or bullish movement. Only if op decide to be trading on a downward direction then he can make some profits from copy trading and also trading. One thing we need to understand about trading is that is good to copy a good trader for a while so one cam learn how the market works and move and also how to reactive at a particular condition of the market.
You can just decided to copy trade without having good idea of the market and how the market moves. The market is so big and wide and we wouldn't want to make a big mistake that will cost us a big blow or regret later.
